![]() | ![]() Title: Structure of the nuclear exosome captured on a maturing preribosome.

We used cryo-electron microscopy to visualize the yeast nuclear exosome holocomplex captured on a precursor large ribosomal subunit (pre-60) during 7-to-5.8 rRNA processing. The cofactors of the nuclear exosome are sandwiched between the ribonuclease core complex (Exo-10) and the remodeled "foot" structure of the pre-60 particle, which harbors the 5.8 rRNA precursor. The exosome-associated helicase Mtr4 recognizes the preribosomal substrate by docking to specific sites on the 25 rRNA, captures the 3' extension of the 5.8 rRNA, and channels it toward Exo-10. The structure elucidates how the exosome forms a structural and functional unit together with its massive pre-60 substrate to process rRNA during ribosome maturation. | ||||||
